11Claim.

1 This invention relates to building blocks and a wall formed thereby, it being one object of the invention to provide blocks formed of plastic material and being of ,suchconsistency that when a wall is formed of the improved blocks 1 and allowed to dry and harden, it will be sub- 1 stantially a solid wall of set plastic which is fire-proof and moisture-proof.

Another object of the invention is to provide blocks which may be molded just prior to use andbuilt into a wall while still damp, mortar between the blocksbeing of the same material from which the blocks are formed so that, after the blocks have been built into a wall, the mortar may be troweled and blended into the blocks to provide the wall with a hard and continuous surface which may be covered with a surface coating or painted. 1

Another object of the invention is to provid building blocks formed of, materials easy to obtain and, when mixed, forming a plasticmaterial which may be moldedunder pressure to the desired shape and form blocks having sufli cient strength to withstand heavy bearing through one of the blocks on the line 2-2 of Fig. 1. 1 1 1 1 N Fig. 3 is a sectional view taken vertically through the wall. 1

The blocks l are formed from a special material and may be of any desired dimensions, it

of :forty thousand pounds and, when the blocks are subjected to a pressure of five hundred The specific quantities set forth are for a block 8 x 8 x 16 inches, and itis to be understood that in quantity production the same proportions will 'be used., The dirt is the ordinary garden variety which may contain sand and gravel, and the clay and sulphite waste liquor 1 are mixed with it in any desired manner. 1 After the mixture has been formed it is placed in molds and pressed to thedesired shape by hand pressure or by power such as hydraulic pressure. The blocks are then removed from the press,

and built into a wall while still damp. The same 1 material used for making the blocks: is usedfas and blocks troweled with a steel trowel to form a smooth surface which is hard as stone when the blocks and mortar have set and are fully dried. The outer surface of the wall is painted with sodium silicate and house paint, as shown at 3 and 4 in Figure l of the drawing, to provide a water-proof finish, and the inner surface of having been found in actual use that blocks f 8 x 8 x 16 inches may be easily handled and form a strong wall. 1 1

- These blocks, are formed with passages. 2 extending vertically through them and so arranged thatwhen the blocks are built into a wall, the

passages register and form airspaces occupying approximately 33% of the bulk of the wall.

I his provides-good insulation for heat and cold dered clay and sulphite wasteliquor which may be either raw or in concentrated form. Forja block of the dimensions mentioned forty pounds of dirt containing one pound of powdered clay is used and with this amount, of dirt, two pints of raw sulphite liquor are mixed. A block of the proportions set forth will withstand more than twenty-four thousand pounds bearingpressure.

When concentrated sulphite waste the wall may be calsomined or papered.

By placing a substantial concrete footingat the base of the wall and erecting the wall thereon and coatingthe exterior surface of the wall with a good commercial water-proofing solu-g tion, such as asphalt or the like, a basement;

wall is formed which is dry and free from seepage. m 1 It is to be understood that the blocks may be of any dimensions and shape desired and that Having thus described the invention, what is claimed as new is:

The method of erecting a wall comprising compressing a mass of material consisting of waste sulphite liquor and dirt containing ground clay and forming the same into plastic blocks, placing the newly formed blocks, while still damp, one ,1

upon another with mortar of thesame material as the blocks between them to form tiers of blocks andinterposed mortar, surfaces of the mortar exposed betweenthe blocks being then smoothed and blended into adjoining portions of exposed surfaces of the blocks to form a wall having a, hard and substantially unbroken surface when the blocks and mortar are set. 1 1
